Application filed June 7. 1.922. SerialNo; 566,498. 7

To all whom it may concern Be it known that I, O'r'ro A. Bnnonm a citizen of theUnited States, andresident of Newtonville, county of Middlesex, State 01 "1 Massachusetts, have invented an Improvement in Combing Machines, of which the following description, in connection with the accompanying draw ng, is a specificat on,

like characters on the drawing representing.

like parts. 7

This invention relates to combing, machines, and particularly to combing machines of that'type which have a fan or suction apparatus for the purpose of removing thewaste from thecircularbrush of the machine and keep'ng ,the machine free from dust during the working. j l

As illustrating combing machines of this i type I, would refer to the following United States patents to Both, No. 905,233, Dec. 1, 1908 and Belger No. 1,106,073, August 4 1914. These combingmachines are usually driven by means of fast and loose pulleys, and the main shaft, which is driven by the fast pulley isoperatively connected to; a, fan shaftfrom which. thefan of the aspirator or other suction deviceis operated.

In operating combing machines of this. typeit is desirable that the fan or suction apparatus should continue to run for a period of time after, the machine has come to rest in order that the suction.-action may con-.

tinue sufiiciently long to remove. all the waste from the cylinder and brush, for if the suction action stops as soon asethe-machine.

stops there wilhbea certain, amount of waste remaining on the cylinder and brush which will be detrimental to the combing operation whenthe machine is again started.

It is also highly desirable that the suction apparatus should beginsto function and that'- suction should be developed as soon as the;

machine starts in operation.

It is neot llGObjBGtSgOf-IHY invention to provide'a novel improved means qfor; op,

erating the fan of -the fcombing machine so that these .desirable. results will be,,attained, that is, the fan will continue to develop suction for apredetermined time after the machine is stopped thereby,completely clearing the cylinder'and brush of waste, and the fan will start upat once when the machine starts sothatthere will be th'epropersuotioniaction developed as soon as the machine is inopera ti onL. I.

I I secure' results by providinganovel construction whereby when the machinefis stopped thefan is allowed to run freely of itsown momentum until it comes to rest and this operationof the fan, will continuethe suction action for a sufficient period of time after the machine has come to rest to clear the cylindersr r Th fan driving mechanism is also con; structed so that when the machine is started up by shipping the belt onto the fast pulley, Y

the fan will be immediately set in operation to produce the necessary suction effect.

. In order to give an understanding of the invention I have illustrated in the drawings a selected embodimentthereof which will now be described after which the novelfeatureswill be pointed out in the appended claims.

Fig. 1 is a side View ofa portion ofthe frame of a combing machine showing the fan-operating mechanism; i K

Fig. 2 is a side view thereof. v

Fig. 3 is a view of the fan-driving mechanism looking from the; opposite side from that shown in Fig. 1 and showing the posi- I tion ofthe parts, when the driving belt is on the loose pulley.

'Fig. 4c shows the position of thepartswhen the driving belt is on the fast pulley.

Fig.6 is'an enlarged section through the link 20 V 7 Inasmuch as my invention relates to the mechanism for driving the fan ofthe aspirator or other suction device of a combing. machine I'fhave not thoughtit necessary to illustrate herein a complete combing-,ma-

chine but haveyonly shown a sufficient portionthereof to enable my invention-to be understood. V r

1 indicatesfa portion of a frame of a combing machine, which is provided with thedriving shaft 2 onwhich is mounted the loose pulley 3 and the fast pulley 4, the pulley. 4 being fast to the shaft2. .5 indicates the driving'belt bywhich the. machine is driven and 6 is the belt shipperby which the belt is shipped from the fast to the loose pulley and vice versa. This belt shipper isshown as carried'by a belt shipper arm 7- pivoted @to theeframe at 8 and having a shipper rod '9 connected to its lower end, as shown at 10.

,110 indicates the" fan shaft from which furnish any support for the elbow lever and the full benefit of the weight 18 is secured in holding the pulley 17 against the belt. When the belt is shifted onto the loose pulley, however, the first movement of the lever 22 will raise the part 34 to bring the nuts 36 against the part 33 and thereafter the link 20 is operative as a strut to raise the elbow lever 15 into the full line position Fig. 2. The purpose of this loose connection in the link 20 is so that when the belttightening pulley-is in its operative position it has the full benefit of the Weight 18 in holding the belt 13 taut.

It will thus be seen that my invention comprehends a driving mechanism for the fan which is constructed so that it will allow the fan to rotate freely under its own momentum after the machine is stopped,

' but will start the fan up instantly when the machine is started, and while I have illustrated herein one construction operating in this manner yet I wish it understood that the invention is not limited to the form shown but may include other constructions which will accomplish, this purpose.

I claim,

1. The combination with a combing machine having a main driving shaft, fast and loose pulleys thereon, a belt shipper by which the driving belt is shipped from one pulley to the other, and a fan shaft from which the fan is operated, of means for driving the fan from the driving shaft, said means including a fan-driving belt which is normally sufiiciently loose so that it is ineffective for power transmission purposes and means operated by the belt shipper to tighten said fan-driving belt when the driving belt is shipped onto the fast pulley and for loosening the fandriving belt when the driving belt is shipped onto the loose 1 fan-driving belt pulley fast on the driving shaft, a belt pulley on the fan shaft, a fan belt encircling the belt pulley and the fandriving, pulley and normally being sufiiciently loose to permit the fan shaft to rotate freely, and means operated by the belt shipper for tightening the fan belt when the driving belt is shipped onto the fast pulley and for loosening the fan belt when the driving belt is shipped onto the loose pulley.

3. A combing machine having in combination a main driving shaft, fast and loose pulleys thereon, a belt shipper by which the driving belt is shipped from one pulley to the other, a fan shaft from which the fan is driven, a fan belt for driving the fan shaft from the main shaft, said beltbeing normally sufliciently loose to permit the fan to rotate freely by its own momentum, a weighted elbow lever ,pivotally mounted on the fan shaft, a belt-tightening pulley carried by said lever, and a connection between said lever and the belt shipper by which the belt-tightening pulley is rendered inoperative when the driving belt is on the loose pulley and operative when the driving belt is on the fast pulley. V

In testimony whereof, I have signed, my name to this specification.
